MILWAUKEE (AP) -- The U.S. Food and Drug Administration said Thursday it will revise proposed livestock feed rules after hearing objections about the potential cost from brewers who sell grain leftover from making beer to ranchers and dairy farmers.

Beer makers big and small feared they would have to pay for grain testing, equipment, audits and other safety measures at an estimated cost of $13.6 million per brewery, likely affecting the price of beer, beef and dairy products. To avoid passing on those costs, some brewers said they would have simply sent the grain to landfills.
